For astronomers, finding a new black hole orbiting an aged red dwarf star is an exciting find in itself, but when that black hole seems to be a "missing link" stellar-mass black hole, you can ...

Black holes are one of the most mysterious cosmic phenomena, despite how much we continue to learn about them. While considered a mathematical possibility for many years, the first black hole wasn ...

Supermassive black holes are some of the most impressive (and scary) objects in the universe—with masses around 1 billion times more than that of the sun. And we know they've been around for a ...

Star explosions called novas are happening twice as often near a gargantuan black hole jet as they are in the rest of the galaxy, and astronomers aren't sure why. Astronomers using the Hubble ...
